IMPROVEMENT IN STOVES;

Specification forming part of Letters Patent No. 47.218, dated April 11, 1865.

ing the combustion and the arrangement of the heating-chamber; Fig. 3,; a plan of the ash-lifter detached.

Like letters of reference indicate corre-- sponding parts in all the figures.

It has long been a favorite idea to intro duce the draft to support the combustion in stoves, furnaces, and fire-placesfrom the outside of the'rooin in which 's'uch'stoves, &c.,

are situated, in order to avoid vitiating the -air of the apartment. Such .a device was adopted by Count Itumford many years ago,

and has been the subject of many inventions since, both in Europe and America. It has also longbeen a favorite idea to introduce the air from the outside into a chamber connected with the stove or furnace, so as:

to -be heated and furnish to the room a con: stant and fresh supply to produce proper ventilation; but in no device with which I am acquainted have both these ideas been combined.

My invention consists, first, in a peculiar arrangement of the base of thestove, whereby the air that is drawn from the outside of the room goes partly to support the combustion and partly to supply a chamber, where it is heated, and where it flows constantly into the room to heat and ventilate it. i 5

As represented in the drawings, A is a'hollow base, B, and provided with a firechamber, 0, whose bottom ais open and ex tends through the flooring D into the cellar. The hollow base B is divided by'a circular partition, b, into two compartments, E G, the former being merely a circular air-passage at the periphery, of suitable size to allow the passage of the necessary amount of air,

and the latter a comparativelylarge central. chamber,- surroumlingthe base of the fire-pot, so as to come near the fire, and provided at its top with perforations c c c, to allow the heated air therein to flow into the room. If

desired, a register may be usedin combina tion with these perforations to graduate the -flow of air at any time. Into the passage E,

on one side of the stove, opens an induction air-pipe, II, which extends into the cellar or beneath the flooring and thence outward into the open air. Communication is had between the passage E and heating-chamber Grby means of an opening, d, in which fits avalve,

f, that the supply may be turned on or off at pleasure. 0n the opposite side of the stove from the opening of the induction air-pipe a draft-tube, I, connects with. the passageE, and, passing through the heating-chamber,

opensiu-to the base a of the-fire-pot beneath the grate. The entrance to the tube I is GOV? ered by a valve, '9, similar'to that which covers the opening to the heatingchamber.

The cold airfrom theinduction-pipcH,drawn from the cellar .or from theoutside, entering the passage E, passes around to the opposite side and aportiou enters the tube I to support f the combustion. In thus passing around the passage E the "cold airbecomcs toa certain degree heated before it enters the draft'tube,

and therefore in better condition to produce combustion than if it entered the fire 'pot directly in'its cold state, as in the case with other or similar devices with which I am acquainted. This, effect of heating the draft. air is also further produced by Jcarryingthe pipe I directly through the heating chamber, where "it is surrounded by'the hot air. At the same time thatthis effect isproduced, a portion of the air from the passage E enters through the opening (1 into the heating-chamberf G.

Here, from the proximity of the chamber to I the base of the fire-pot which it surrounds, the. stove of any ordinary construction, resting on airbccomes rapidly warmed and flows coustantly through the perforations a 00 into the room, thus producing a constant supply of, pure air and properly ventilating the apart ment. It will be seen'that at any time either of the valves f 9 may be closed, thus turning I off the supply to either the draft-tribe or heating'chamber. This arrangement.is'-'very simplc, cheap, and convenient, and occupies no extra space. The base Bis. of a shape similar-to that employed in many stoves In or- (linary' devices,- where-ii heating-chamber is e nployed, the chamber is situated up 'within thei sto've and not at the-base. In mine it is situated at the base,whieh nakes it especially convenient for warming thefreh, In simple, :ordina ry radiatingcoal-stoves the bottom'is always cold; and this is a great objection to their use.. I overcome these popular objections,. while I at the same time produce posi- I iive'advan tages which I believe are new. p

What I claimv as my inventior, and desire --to'secure by Letters Patent, is

The special arrangement -for. supplying the air'dr2.w1 1"fr0m the onts idefcf the mom partly to support the combustion and p1 11y to supply the room, the same consistingbf the passage E, central .heating chamber,- G, the

induction-pipe 'H, and draft-pipe I, operating" substantiallyin the manner and for the purpose herein set forth.

. In witness whereof Ihavc liei'euntosi'gned my name. in the presence of twosubscribing witnesses.
